alsa: clamp buffer_frames correctly

Browse source 
Don't try to multiple the max_buffer_size with the frame scale or else
we might try to set a min_buffer_size larger than the max_buffer_size.

Instead, use the frame_scale only to scale the quantum_limit and then
clamp against the max_buffer size.

See #3000
